Specification of Letters Patent.

Patented Oct. 12, 1915.

Application filed January 28, 1914. Serial No. 814,858.

To all whom it may concern Be it known that I, FRANK C. Unsrsnocn, acitizen of the United States, residing in New York city, in the countyof New York and State of New York, have invented certain new anduseful'Improvements in Type- Writing Machines, of which the following isa specification.

My invention relates to 'typewrltrng machines, in which a travelingcarriage 1s shift- ,able into cooperative relation to either one of aplurality of sets of type-bars, and the invention relates particularlyto mechanism adapted for tabulator work with e ther type set alone orfor shifting the carr age from its position into cooperative relation toone type set to a predetermined position in rela tion to another typeset.

In my co-pending application, Serial Number 810,712,'I have shown twomach ne frames placed side by side, each comprising a complete typesystem and a traveling carriage mounted to travel on a track extendingthe full length of the two machines, whereby the carriage may have aletter-feed movement in cooperation with either type system, and mayalso be moved from one type system to the other. 7

The present invention may be combined with a machine as above described,and may comprise a swinging rack on each frame, said racks each providedwith tabulator stops adjustable along the racks to different columnarpositions, said stops movable with the rack into the path of thecarriage to stop the latter in the positions for which the stops areset. Either rack may be actuated by a key which swings the stops intooperative position, the movement of the rack serving to release thecarriage from its escapement mechanism and permitting it to run forwarduntil arrested by a stop.

In order that the carriage may be shifted from one type system to theother by the referred to, and in accordance with-the present invention,one or more columns or vertical sections ofthe work-sheet may be writtenwith one set of types, and other portions with the other set, as thecarriage may be moved by operating a shift key, from one type zone andcolumn position to the other type zone and a new column position.

Other features and advantages will here inafter appear.

In the accompanying drawings, F1gure 1 1s a rear elevation view of amachine embodying the principles of my invention.

Fig. 2 is a detail perspective view of the means for connecting the tworack frames. Fig. 3 is a part sectional rear elevation view of the same.Fig. 4 is a sectional elevation of a swinging rack frame and escapementmechanism, the parts being in the position assumed when a tabulator keyis depressed. Fig. 5 is a similar view, but with the tabulator keyreleased and the parts in their nor mal position of rest. Fig. 6 is adetail view showing different sized types.

The two machine frames 1 and 2 may be mounted side by side on a base 3,the frames shown being those of the Underwood typewriting machine. Apaper carriage is mounted to travel on front and rear rails 5 and 6which may extend from the-outer end of one f ame to the outer end of theother frame reby the carriage may be moved from one frame to the other.Mounted on each frame is a type system comprising a set of type-bars 7adapted to be swung upwardly and rearwardly against the front face ofthe platen 9 mounted on the carriage 4. The type-bars 7 carrying types 8are operated by keys 10 on key levers 11 fulcrumed at 1.2 and connectedthrough sublevers 13 to the type-bars which are pivoted on the fulcrumrod 14:.

The carriage is propelled in its letter-feed movement by-a spring drumor motor 15 connected through a draw band 16 to a lug 17 on thecarriage. When the carriage is in ,riage at 26, which frame may beoperated by a finger-piece 2''? to li t the rack and release thecarriage from the escap'ementpermit the carriage to run mechanism andforward.

The carriage, when released-by thje key 27 may be moved along the railsSand-'6 into a position to coiiperate with the'type system comprising;keys l0 'opera'tively connected to types 8 on the frame 2.-The-letter-feed movement of carriage when in such po- ,sition iscontrolled by a mechanism similar to that just described, and which maycomprise a rack 28 to run in mesh with a pinion 29 connected to anescapement wheel 30, controlled by escapement dogs on a rocker 31,actuated by the type-bars on the frame 2.

It will be noted that the escapement pinion 29 is of greater diameterthan the escapernent pinion 19 on the frame 1, whereby the letter-feedmovements of the carriage when opposite the types 8* on the frame 2 areof greater extent than those for the types 8 on the frame 1, thusproviding for different sized types in the two type sets. The difference in letter-spacings for the two type systems could be provided invarious other ways, as for example, by varying the rela tive number ofteeth on the escapement wheels 20 and 36, or making the spacings of theteeth on one of the racks 18 and-28, greater than on the other. Theletter-spacings fonthe two systems might also be made equal if desired,in which case a single letter;feed rack on the carriage would preferablybe employed.

The mechanism which may serve the purpose of the usual tabulatormechanism employed on the Underwood machine, and which may further beused for shifting the carriage from one type system to the other andbringing it to rest at any column or lettor-space position for the typesystem to which it is shifted, will now be described.

Onthe machine frame 1 is mounted a swingingrack frame comprising a lowerhorizontal bar 32, a rack bar 33, and ends 34: and 35, said frameprovided with pivots 36 and 37 by which the rack frame is mounted on themachine frame 1. The pivot 36 may have its bearing in a block 36*,secured to th frames 1 and 2. Column stops 38 slidably mounted on a rod39' of the rack frame, are

provided with teeth adapted to interlock with the teeth 40 on the rack33 to hold the stops in any position ofadjustment along the rack, andeach stop is provided with a forwardly extending lug or projection 41which, when the rack frame is swung forward, is in the path of a stop4.2 on the 08.1 riage,

The rack frame is swung forward to op erative position by means of atabulator key 43 on a lever 44 fulcrumed at 12 and connected through alink 45, to an arm 46 on the rack frame. When the tabulatior key isdepressed the carriage feed rack 18 is lifted from the pinion 19 torelease the carriage from the letter-feed escapement mechanism by meansof a roller 47 on a lever 43 pivoted at 49, and actuated by a lug 50projectingforward from the rack frame. Thus when the tabulator key 43 isdepressed the stops 38 are swung forward and the carriage released andpermitted to be drawn forward I by the motor 15 until the first stop 38in the path of the lug 42 arrests the carriage.

Similar tabulator mechanism may be provided on the frame 2; suchmechanism, .comprising a frame consisting of bars 51 and 52 connected byends 53 and 54: having pivots 55 and 56. Stops 57 are adjustable alongthe rack bar 51; It will be noted that the teeth on the rack 51 arespaced at wider intervals than the teeth on the rack 33, the spacing ineach instance being preferably the same as that of the letter-space feedof the carriage. Each of the stops 38 and 57 is preferably provided witha pointer158 to indicate on a scale as 59, the letter-space position atwhich the carriage may be arrested by the step In order thatthe carriagemaybe shifted from one type zone to the other by the operation of thetabulator key 43 and be arrested in any desired position, determined.

by the setting of a stop 57, the two rack frames are connected to swingthe unit.- For this purpose, a connection, as shown in Figs 2 and 3, maybe provided; such a connection comprising a, rod 60 having a stem 61threaded into a hollow rod or sleeve 69', the

rod 60 connected to the frame end 53 by a screw 63, and the rod 62connected to the frame end 34; by a screw 64. An adjustable but rigidconnection between the frames is thus provided, whereby when either rackbar is swung forward by the operation of a --tabulator key, the otherrack bar swings with it.

The rack-frames, being rigidly connected and concentrically hinged, maybe adjusted endwise simultaneously by suitable manipulation of the pivotscrews 37, 56, at the ends of such double rack-frame; and if it be foundthat either rack-frame is out of its true relationship to the escapementmechanism associated therewith, its pivot screw rate the frames more ordraw them together riage will be released from the control (if theescapeinent mechanism 22, Fig. 1, and permitted to run forward into theZone of the type system on the frame 2. The rack 51 on the frame 2 willalso be swung forward and hold the letter-teed rack 28 oil theescapement pinion 29 so that the carriage can continue its forwardmovement until ar-.

rested at a predetermined position by a stop 57 on the rack 51. Theletter-teed racks on the carriage may be of suflicient length to beengaged by both rollers l7 as the carriage passes from one printing zoneto the other, thus preventing the feed racks from dropping at thispoint. The arrangement just described for shifting the carriage from oneprinting zone to the other is of great convenience for tabulator work inwhich one or more columns in the work-sheet are adapted to be written byone set of types and other columns by a different set of types. Thestops 38 may be adjusted for bringing the carriage to ditlerent columnpositions for writing tabulator work along the. left-hand side of thework-sheet, and the carriage then shifted by operating the key 43, forwritin with a different set of type in other columns along theright-hand side of the sheet. In some kinds of work the tabulator stops38 may he set to in-opcrative position and the key d3 used simply forshifting the carriage from one type zone to a predetermined position inthe other type zone. Thus, part of a line may be written with one set oftypes and the key i3 then depressed to position the carriage forcompleting the line with the other set of types. A tahulator key (35 ispreferably provided on the frame 2. Either key 43 or 65 may he used toactuate the tabulator rack bars.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
